Nepal trekking experience: 1994: Sept - Oct - Lake Ra-Ra, Tatopani. 2005: Oct - Nov - Annapurna circuit (AC) and sanctuary (ABC), then Everest region - Gokyo and EBC, via Cho La pass. I trekked solo and independently, but with others I met "on the road". 2008: April - May - AC and ABC, including side trip to Lake Tilicho Tal. Then to Gokyo, day walk up Renjo La and back. Again trekked solo and independently - fewer other trekkers than in 2005. 2010: Jan - 3 high passes in the Everest region, first time I had trekked with a guide (whom I had met by chance in May 2008). 2010-11: Dec - Feb - walked in from Jiri, then the 3 high passes again, then after 4 nights in my guide's village, Langtang, Gosainkunda and Helambu. 2012-13: Nov: 5 nights in my guide's village (Tihar festival), then Langtang - Gosainkunda - Helambu (west side). Dec - Jan: Annapurna Circuit, including Kang La pass, and going near to Dhaulagiri Icefall. Then 3 more nights in my guide's village, and 2 nights in another Nepali friend's village.
